3 Claims.

This invention relates generally to hydrocarbon burners, more specifically to that type of burner in which the fuel burns without the admixture of atomizing agents, such as steam or 4 compressed air.

a quickly installed in a furnace or the like.

Otherobjects and advantages will be apparent from the following description, reference being had to the accompanying drawings, in which:

Fig. 1 is a top plan view of the burner, parts 4 .0 being broken away and shown in section.

Fig. 2 is a front elevation.

Fig. 3 is a vertical section taken on line 33 of Fig. 2.

Fig. 4 is a longitudinal section taken on line 5 4- 1 of Fig. 3.

Referring more specifically to the drawings, 10 generally designates a pan or retort into which the hydrocarbon fuel is continually converted into gaseous state in a manner hereinafter described.

Formed integral with and extending across the forward end of the pan is a distributor or manifold 12 which communicates with the pan through a plurality of horizontally disposed ducts l4 and is adapted to be kept filled with oil from a suitable source of supply such as a static pressure tank (not shown) through a pipe line 16 controlled by a stop valve 18.

Screw threaded in openings formed in the upper wall 19 of the distributor is a plurality of needle valves 20, the points 21 of which register with ports 22 communicating with ducts 14. Valves serve to regulate the flow of fuel from the distributor into the pan, and are adapted to be individually adjusted so that an equal amount of said fuel will pass through each of'said ducts, the valve being provided with square heads or the like 23 for this purpose.

Referring to Fig. 3, the bottom 24 of pan 10 is slightly inclined (i. e. slants downwardly toward its rear end wall 25) and formed on its upper face is a plurality of upraised surfaces 26, the side faces of which form channels 28.

Channels 28 converge toward their rear ends as clearly shown in Fig. 1 and serve to evenly distribute the fuel discharging from ducts 14 over' the surface of the pan.

Extending upwardly from sides of the pan are walls 29 upon which are mounted a horizontally disposed plate 30 having an upstanding flange 31 and positioned between said walls is a vertically disposed plate 32.

Plate 32 is adjustably supported by set screws 33 threaded in lugs 34 formed on each end thereof which in turn engage lugs 35 formed on the plate 30. The inner face of plate 32 engages offset portions 36 of the side walls, and is held in place by screws 37 threaded therein and engaging its outer face. The bottom of the pan 1%) together with plates 30 and 32 form a combustion chamber or retort designated at C.

Adjustably mounted on the plate 32 and extending below the lower end thereof is a plurality of tongues or deflectors 40 which serve to direct the current of air passing through the combustion chamber into contact with the fuel as it is converted into gas while passing through the channels 28.

Deflectors 40 are preferably formed from thin metal strips, the lower ends of which are preferably bent rearwardly as shown in Fig. 3, and are adjustably secured to plate 32 by screws 42 extending through slots 43 formed in the upper portion of the deflectors.

Projecting from the front face of the plate is a stud or handle 44 by which the plate may be raised or lowered when required.

Mounted in a chamber 46 disposed below pan 10 adjacent its forward end is a perforated pipe 47 adapted to be connected with a fuel supply (preferably illuminating gas) through a pipe 48 controlled by a valve 49. The pipe 47 forms a burner to heat the fuel in the pan, i. e. to render it combustible, the heat being varied according to the gravity or viscosity of the oil employed.

As previously referred to. chamber 46 extends underneath pan 10, the bottom wall 50 of which has an outwardly flaring portion 51 adjacent its forward end to accommodate the burner pipe 4'7.

Pipe 4'7 extends through aligned openings formed in the side walls 52 of chamber 46 and is held in place by set screws or the like 53 threaded in openings formed in the bottom wall of the chamber.

Arranged adjacent the forward end of chamber 46 is a pivotally mounted door or damper 54 which serves to regulate the draft passing through said chamber in relation to the flame of the burner.

Damper 54 is preferably formed of sheet metal and is pivotally mounted at its upper end on a rod or wire (extending across the front face of the distributor 12) the opposite ends of which are held in place by the heads of screws 56.

Formed on the bottom of chamber 46 and side walls 29 is a lateral flange 57 which, together with flange 31, are adapted to be connected by bolts or the like 58 to the wall 59 of the furnace or fire box.

In operation. the pan is adapted to be preheated with. theburner pipe 47 until it becomes sufficiently hot to vaporize the fuel. Valve 18 is then opened sufficiently to allow fuel to flow from the ducts 14 into the distributing channels 28, wherein it is converted into a gaseous or combustible state through contact with the bottom of the pan. A torch or the like is then applied to ignite the gas thus generated and valve 18 adjusted according to heat required. Thereafter valve 49 should be adjusted to reduce or cut off the supply of fuel to the burner pipe 47.

Fuel then continues to vaporize in the channels within the combustion chamber C and ignites at a point slightly rearwardly of the deflectors 40 due to the velocity of the current of air passing therebetween, while at the same time the combustion is increased due to air passing through openings 60 formed in plate 32 into the combustion chamber.

I claim:

1. A burner of the character described comprising a fuel vaporizing pan having upwardly extending side walls and a plurality of channels formed in the upper face of its bottom, a fuel inlet distributor in said pan adjacent one end thereof having a plurality of discharge ducts formed therein communicating with said distributing channels, a plurality of needlevalves mounted in said distributor in register with said discharge ducts, a horizontally disposed plate secured to the side walls of the pan, a vertically disposed plate extending between the side walls of said pan and a plurality of deflectors secured to and extending below the bottom edge of said plate.

2. A burner of the character described comprising a fuel vaporizing pan having a plurality of distributing channels formed in the upper face of its bottom and a chamber disposed therebelow, a fuel inlet distributor in said pan adjacent one end thereof having a plurality of discharge ducts formed therein communicating with said distributing channels, a plurality of valves mounted in said distributor in register with said discharge ducts, a plate disposed between the side walls of said pan, a plurality of deflectors secured to and extending below the bottom edge of said plate, a preheating burner disposed in the chamber below said pan, and a damper for regulating the volume of air passing through the chamber.

3. A burner of the character described comprising a fuel vaporizing pan having a bottom disposed in an inclined plane and a plurality of distributing channels formed in the upper face thereof, a hollow fuel inlet distributor formed integral with and extending across said pan adjacent its highest end, there being a plurality of discharge ducts formed in said distributor and communicating with the distributing channels in said pan, a plurality of needle valves screw threaded in openings formed in said distributor with their points in register with said discharge ducts, a vertically disposed plate extending between the side walls of said pan, a plurality of deflectors secured to and extending below the bottom edge of said plate, and a perforated burner pipe disposed below said pan for preheating fuel discharged from the distributor onto said pan.
